Knowledge about the permeability of surrounding rock (salt rock and mudstone interlayer) is an important topic, which acts as a key parameter to characterize the tightness of gas storage. The goal of experiments that test the permeability of gas storage facilities in rock salt is to develop a synthetic analogue to use as a permeability model. To address the permeability of a mudstone/salt layer...

An improvement of the pulse decay method rock permeability measurement is presented. The technique based on fitting experimental data to analytical and numerical solutions filtration equations derived with regard variation flowing gas properties temperature pressure. A special apparatus software for implementation this were developed. single experiment in which used as a medium enables determin...

Gas flow in nanoporous rocks is closely relevant to several globally important energy and environmental issues, such as shale-gas production CO2 subsurface sequestration. The Klinkenberg effect critical an understanding of gas flow, yet many specifics are unclear for rocks. Here we investigated the on basis a systematic study permeability diffusivity under range pore pressures varying water sat...

Liquid permeability of sedimentary rocks is relevant in several contexts, but gas easier to measure, so liquid typically estimated from via empirical or semiempirical correction procedures. A frequently used and trusted procedure the well-known Klinkenberg correction, which based on pressure dependence permeability. However, gaseous flow-through experiments a series Fontainebleau, Castlegate, B...

Permeability is an important parameter in the process of coalbed methane exploitation. To improve production efficiency and explore control mechanism gas flow law coal, permeability helium nitrogen same coal sample was tested under different effective stress (the difference between external pore pressure mass) by using seepage device. Based on theory, interaction stress, adsorption effect Klink...
